How To Store Flour To Prevent Bugs

Sugar and flour can be found in almost all kitchens, since they’re the two basic pantry staples, going back to our parents’ or grandparents’ cupboards. These two staples are so popular because one: most recipes call for either flour or sugar or two: because they can last for much longer without perishing.

That leads us to the next point, proper storage. Perhaps you simply buy your bags of sugar or flour and store them as they are, if that works for you, great! However, bear in mind that this could also open you up to pest or flour bug infestations, known as “weevils.” 

Not only is the idea of these creatures unpleasant, but this can also lead to other issues like mold and unwanted larvae in your food. Furthermore, improper storage of flour and sugar can also turn it rancid quicker, rendering it unusable

If you’re unlucky enough to have had a couple of infestations of your own, or you wish to learn how to avoid them in the future, we’ve crafted this handy guide on how to store flour to prevent bugs, and keep it fresh for longer.

What Is The Best Packaging?

What Is The Best Packaging

If you’re planning on using the grains or sugar in a short amount of time after buying, chances are you won’t experience bug infestations or spoiling. Regardless, make sure that the packets don’t have any small holes or tears, or carry a rancid smell. This smell is due to oxidation, when the product is exposed to air or moisture over long periods of time, causing it to go off.

If you’re planning on storing the dry staples for a while, invest in a large, airtight container, preferably made from glass or metal. These containers usually come with strong, protective seals around the edges, preventing any bugs from getting in. Just regular paper or plastic packaging will do very little in protecting your flour from weevils.

Lastly, before storing your dry goods, go over the shelves with a cloth to ensure no crumbs or spills attract unwanted visitors. It’s best if you store them in cool, dark locations, such as a pantry, if possible.

Best Flour Containers

As mentioned above, the best type of containers are either made from glass or metal and have tight-fitting lids, such as screw-top ones. These can also be a lot more convenient since they help your goods more organized and prevent spills, especially if you use a flour scoop.

Dry food containers are also a lot more hygienic, and easy to wash too, plus they can really add a nice decor to your kitchen, and you can store practically anything in them. If you want to go all out, you can also attach a label on each one, stating the date of purchase – to keep track of your goods.

Where Should I Keep My Flour?

Now that you know the type of container you should store your flour in, let’s talk about the location. While your kitchen cupboard might be the obvious choice, flours and grains actually store pretty well in the fridge or freezer, too. This option is good if you’ve frequently experienced infestations, or you’re very concerned about getting one. This method keeps your flour fresh for up to one or two years.

If you decide to store it in the freezer, make sure to invest in an airtight, freezer container, to avoid any moisture from getting in. Also, this method doesn’t apply to sugar, as storing it in the fridge can cause it to go lumpy.

Otherwise, when keeping dry goods in the cupboard or pantry, make sure it’s away from other strong-smelling produce, such as onions or garlic. The same goes for cleaning products, like soap or washing powder. This way, your flour should last a good six to eight months.

How To Get Rid of Flour Bugs

Flour bugs, or weevils, are attracted to damp, warm places, such as your kitchen cupboards. They are usually drawn in by flour or any other spills, so be sure to keep that area clean at all times. Additionally, they can also arrive home from the store-bought package of flour. You’ll know it’s infested if you notice a brownish surface sitting at the top of the product – these are the eggs laid by female weevils.

If you’re unsure, rub some of the contaminated flour between your fingers, if it has a sort of a minty smell, it’s the bugs. The eggs will hatch in about one to five months’ time, unless thrown out straight away, preferably while wrapped up in something.

How To Keep Flour Fresh

Here are some more tips on how to store flour long term, and prevent future bug infestations from occurring:

  • As mentioned above, sticking a label with the purchase date and the name of the products will help you keep track of the flour’s use-by date, while keeping it nice and organized, too.
  • Keep in mind that whole-grain produce like spelt, barley, and wheat spoil much faster, lasting only three to six months. Try keeping them in the fridge or freezer to extend their life.
  • Generally, most types of flours have a good one to two years in them, but be sure to follow its original date, and make sure the smell doesn’t turn rancid. If it does, toss it out, otherwise, you could get sick if ingested.
  • Different types of seeds, nuts, rice, or flax store way better in the freezer, lasting up to a year. If you notice a sour/burnt, they have gone off.
  • Try not to buy excessive amounts of flour or sugar if you don’t need it, to prevent spoilage and waste.

Lastly, do not mix new, unopened packets of dry goods with the old ones. This can cause cross-contamination and significantly shorten the life-span of the new product.
